To all whom it may concern; 7 Be it known that I, VVERNER SCHILLING, a citizen of the German Empire, and residing at Duisburg, Germany, have invented certain new and useful Improvements in Couplings for Wagons, of which the following is a specification.

My invention relates to couplings for wagons especially mine-wagons, and a' prlmary ob ect is to provide an improved coupling which is simple, strong and short and has the special advantage that it can be coupled and uncoupled by one hand. To this end, the coupling members are not only slit in 7 known manner at one place and pushed one over the other at the slits, but the ends made by the cuts are pointed and the coupling members are simple oval rings. As the coupling member consists solely of an oval ring suspended in the eye of the delivery wagon it can be freely moved by one hand and placed crosswise as is necessary for suspending it in the other ring depending from the other wagon. This suspension is facilitated by the ends being formed not as formerly like sharp cutting edges, but as points. The rings after being hung one in uncoupled and, on'the other hand, when out of use they always hang so that the coupling member held by one hand can be inserted The oval form of ring is in itself not new in the art, inasmuch as closed rings like the links of chains have heretofore been used as loose couplings; further, harness hooks are u 7 sides and provided with pointed ends at the out. By transferring these two features known in themselves and comblning them in a delivery wagon coupling I obtain an improved coupling having material advantages in manipulation.

To these ends, the invention consists in the construction, arrangement and combination of parts described hereinafter and pointed'out in the claims.

A preferred form of my invention is represented by way of example in the accompanying drawing, wherein Figure 1 is a side elevation showingthe improved coupling in its tensioned position, Fig. 2 is a like view of one coupling member alone,'and Fig. 3 is a top plan view of the member shown in Fig. 2.

Referring to the drawing, the coupling members are twofoval rings a and Z) which are respectively freely suspended in the links 6 and f mounted on the delivery wagons c and (Z, respectively. The rings a: and b are cut through and according to my invention the cut ends of each of these cut rings are provided not only with the slanting or beveled faces 9 and h, but also with the slanting or beveled face i, so that points k are formed in contrast to former constructions in which the cut ends were only beveled in two planes so as to form a line of intersection and it is possible to insert the two rings .into one another when the one 'ring, as w, hangs vertically downward,

while the other ring, as b, is turned slantwise. In consequence of the form of the points the ring I) need not be turned more than an amount which is readily possible although it is suspended in the link From this it will be understood that the coupling inclined directions toward each other, said cut through portion being relatively narrow at the inner periphery of said ring and relatively wide at the outer periphery thereof.

2. In awagon coupling, an oval coupling ring having one of the long sides thereof cut through, the cut ends of said ring being pointed, the surface of said points extending in oppositely inclined directions toward each other, and being leveled in more than two planes, said cut through portion being relatively narrow at the inner periphery of said ring and relatively wide at the outer periphery thereof.

3. In-a wagon coupling, the combination with two freely hanging links, supported in stationary eyelets, and two matched coupling rings freely suspended in said links, said rings being of oval shape and having one of their long sides cut through, the cut ends of said rings being pointed, the surfaces of said points extending in oppositely inclined directions toward each other, said cut through portion being relatively narrow at the inner peripheryof said ring and relaother and substantially 45 at either side tiyely Wide at the outer periphery thereof, as my invention, 1 have signed my name in said out through portions permitting coupresence of two subscribing Witnesses.

pling of said rings at any position between i right angular position with respect to each VERNER SCHILLING Witnesses:
